Hi everyone,
Im having issues with the following code running as a kernel thread. when i do
the prinft (which i traced with kgdb) it crashes...but those two variables that
i print out, are fine if i do comparisons or store them into variables...only
printing them causes a panic. anyone have any ideas in what im doing wrong?
static void kernmon(void);
static void kernmon_thread(void);
static void kern_print(void);
static struct kproc_desc kernmon_kp = {
"kernmon",
kernmon_thread,
NULL
};
SYSINIT(kernmon, SI_SUB_KERN_MON, SI_ORDER_FIRST, kproc_start, &kernmon_kp)
static void
kernmon(void)
{
kern_print();
}
static void
kernmon_thread(void)
{
int nowake = 0;
for (;;) {
kernmon();
tsleep(&nowake, curthread->td_priority, "-", 7*hz);
}
}
static void
kern_print(void)
{
struct proc *p;
FOREACH_PROC_IN_SYSTEM(p) {
mtx_lock(&Giant);
PROC_LOCK(p);
printf("%d %d\n", (int)p->p_stats->p_ru.ru_isrss,
(int)p->p_stats->p_ru.ru_idrss);
PROC_UNLOCK(p);
mtx_unlock(&Giant);
}
}
